Which two statements are true regarding Oracle Data Pump? (Choose two.)
A.
EXPDP and IMPDP are the client components of Oracle Data Pump
B.
DBMS_DATAPUMP PL/SQL packages can be used indedendently of the DATA Pump clients
C.
Oracle Data Pump export and import operations can be performed only by users with the SYSDBA
privilege
D.
Oracle Data Pump imports can be done from the export files generated in the Original Export
Release 9.x
E.
EXPDP and IMPDP use the procedures provided by DBMS_METADATA to execute export and
import commands
The DBMS_DATAPUMP package is used to move all, or part of, a database between databases, including both data and metadata.
DBMS_METADATA package – retrieve metadata and also to submit XML.
The Export utility provides a simple way for you to transfer data objects between Oracle databases, even if they reside on platforms with different hardware and software configuration
The Data Pump clients, expdp and impdp, invoke the Data Pump Export utility and Data Pump Import utility, respectively. They provide a user interface that closely resembles the original export (exp) and import (imp) utilities.
The expdp and impdp clients use the procedures provided in the DBMS_DATAPUMP
Data Pump Export and Import – for nonprivileged users, the database administrator (DBA) must create directory objects for the Data Pump files that are read and written on that server file system.

Oracle Data Pump is made up of three distinct parts:
The command-line clients, expdp and impdp
The DBMS_DATAPUMP PL/SQL package (also known as the Data Pump API)
The DBMS_METADATA PL/SQL package (also known as the Metadata API)
The Data Pump clients, expdp and impdp, invoke the Data Pump Export utility and Data Pump Import utility, respectively.
The expdp and impdp clients use the procedures provided in the DBMS_DATAPUMP PL/SQL package to execute export and import commands, using the parameters entered at the command line.
These parameters enable the exporting and importing of data and metadata for a complete database or for subsets of a database.
When metadata is moved, Data Pump uses functionality provided by the DBMS_METADATA PL/SQL package. The DBMS_METADATA package provides a centralized facility for the extraction, manipulation, and re-creation of dictionary metadata.
The DBMS_DATAPUMP and DBMS_METADATA PL/SQL packages can be used independently of the Data Pump clients.
